Silhouette Island was an island located in the Seychelles.

After Sam joined him, the Eighth Doctor took her to Silhouette Island, where they were captured by a Rhiptogan bounty hunter called Ruduse. After Sam was poisoned by an alien plant, the Doctor gained an ally in a fugitive Ladeeth, who sacrificed himself to trap Ruduse in a spaceship before it exploded. Back in the TARDIS, the Doctor successfully cured Sam. (AUDIOBounty)
